A spring filter (100) connected to a pump of an embodiment of the present invention comprises: a filtering room casing (110) having an upper panel (113) formed on an upper side thereof, a lower panel (112) formed on a lower side thereof and having a lower penetration hole (112a) penetrating through a central portion thereof, and a filtered water discharge pipe (Po) penetrating one side of an outer circumference surface of an upper end unit; a compression spring (141) disposed on an upper lateral surface of the lower panel (112) in the filtering room casing (110); a compression spring support panel (142) disposed inside the filtering room casing (110) to be in contact with an upper end unit of the compression spring (141); and an operation handle axis (Hs) installed vertically on an upper lateral surface of the compression spring support panel (142) and having an upper end unit protruding outside the upper panel (113), and thus, ground water pumped through the lower penetration hole (112a) is filtered by passing through the gaps of the coils in the compression spring (141), which is in a compressed state, and discharged externally through the filtered water discharge pipe (Po). Thus, according to the spring filter connected to a pump and a filtering and backwashing method using the same, the spring filter of the present invention is directly connected to a pump outlet, and a filtering apparatus is configured at a height half of conventional filtering apparatuses and does not require a separate foundation work, thereby having effects of being inexpensive to produce and maintain and having a simplified washing and backwashing process. |
